These 10 x 13 x 2 inch expansion poly mailers are built from 2.5 mil polyethylene with a gusseted bottom that expands to accommodate items up to 2 inches thick — handling bulkier flat goods that standard poly mailers cannot fit.

E-commerce sellers, subscription box operations, apparel brands, and fulfillment centers rely on these mailers for softgoods, folded garments, multi-item orders, and padded document shipments where standard flat mailers fall short. The white exterior accepts labels, ink, and stamps directly without additional prep, while the silver interior lining adds an extra layer of protection for contents.

A self-seal adhesive strip closes securely without tape, and a double-perforation tear strip gives recipients a clean, easy open. Reinforced seams maintain structural integrity when contents approach full capacity. Each case contains 100 mailers.
